GEORGE W. HINCHMAN, OF GLENWOOD, INDIANA.

MOWING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 686,405, dated November12, 1901.

Application filed June 11, 1901. Serial No 64,139. (No model) To allwhom it may concern:

Be it known that I, GEORGE W. HINCHMAN, a citizen of the United States,and a resident of Glenwood, in the county of Rush and State of Indian a,have invented a Mowing-lilachine, of which the following is aspecification.

The object of this invention is to'provide simple and effectivemechanism for driving the cutter-bar of a mowing-machine, whereby therotary motion of the axle upon which the ground-wheels are mounted isconverted into a reciprocating motion applied directly to the cutter-barthrough the intervention of a pair of tappet-wheels mount-ed on the mainaxle; a rocking bar having a cross-head which is struck by thetappet-wheels*alternately to rock said bar, said rocking bar having acrank on its outer end by which it is connected to the rod whichoperates the cutter-bar, and means for throwing the parts out ofoperation.

The following specification enters into a detaildescription of myinvention, reference being had to the accompanying drawings, and toletters of reference thereon, which indicate the different parts, andwhat I claim in the particular construction and combination is morespecifically set forth in the appended claims.

In the drawings, Figure 1 is a plan view of a mowing-machine constructedin accordance with my invention. Fig. 2 is a longitudinal sectional Viewon the line 2 2 of Fig. 1. Fig. 3 is a detail view illustrating thegearing between the tappet-wheels and rocking bar. Fig. 4 is a detailview of the sectional rocking bar.

Referring to the drawings, A designates the axle of the mowing-machine,upon the ends of which are fixed the ground-wheels B B in order that thesaid axle may turn with the ground-wheels and serve to operate thecutter-bar in the manner hereinafter described.

Mounted upon the axle A is a suitable frame 0, which provides a supportfor the drivers seat c'and is extended forward, as shown, to form abearing for the rocking bar, through which motion is transmitted to thecutter-bar of the cutting apparatus.

D D designate tappet-wheels which are located upon the central portionof the axle A and are fixed thereto in any suitable manner. Thesetappet-wheels face each other, and between the same, upon the shaft A,is loosely mounted a bracket E,having lugs e eithrough which passes asectional rocking bar F F, the said rocking bar being supported at itsouter end by the extension 0 of the frame 0. This rocking bar is made upof two parts or sections F and F, the tubular section F being slidableupon the rear end of the section or bar F, the said sections beingconnected by an ordinary spline or feather, as shown in Fig. 3. At theforward end of the tubular section F is a crosshead f, which is engagedby the tappets d on the tappet-wheels D, and at the rear end of saidsection is a collar f, fixed thereon and connected by yoke s to ahandlever S. Upon the rear end of the tubular section F of the rockingbar, in advance of the aforesaid collar f, is an adjustable collar fbetween which and the lug e is interposed a helical spring 15, whichspring serves to keep the cross-head in line with the tappets,and saidcross-head may be moved out of operation by moving the hand-lever Sforward, sliding the tubular section F upon the bar F. It will be herenoted that the arms of the cross-head and the tappets are beveled, asshown in Fig. 3, so that in case of an accident to the cutting apparatusby reason of anything catching between the fingers the cross-head wouldbe moved forward against the force of the spring, and thereby preventserious injury to the machine. TheZadjustable collar f provides forincreasing and diminishing the tension of the spring. The tappets engagethe crosshead alternately, so as to rock the bar, and this rockingmovement of the bar is converted into a reciprocating motion, impartedto the cutter-bar L by means of a crank H, to which the connecting-rod Iis attached.

The finger-bar M of the cutting apparatus may be hinged to the forwardpart of the frame 0 in the usual manner and any suit able levermechanism provided for elevating the cutting apparatus out of operativeposition. The machine is also providedwith a tongue at and with anordinary shoe a.

From the foregoing description, in connection with the accompanyingdrawings,, the operation of the driving mechanism for the cutter-barwill be readily understood, for the rotation of the axle as the machinepasses over the field will turn the tappet-w-heels D D, and

the tappets of said wheels respectively engaging first one arm of thecross-head and then the otherwill rock the bar and by means of the crankwill impart a reciprocating motion to the cutter-bar. This mechanismpro- -vides a positive operation, and comprising 7 may be housed by asuitable casing.

Having thus described my invention, I claim-- 1. In a mowing-machine,the combination with the axle, of tappetwheels mounted thereon, arocking bar extending between the tappet-wheels and comprising twosections slidable one upon the other, a cross-head mounted upon theslidable section, and a spring adapted to hold the cross-head normallyin line with the tappets, the rocking bar having a crank to which theconnectingrod of the cutting mechanism is attached, substantially asshown and described.

2. In a mowing-machine, the combination with the axle, of tappet wheelsmounted thereon, a rocking bar extending between the tappet-wheels andcomprising two parts slidable one upon the other, a cross-head mountedon the slidable section of the rocking bar, a grooved collar connectedto said slidable section, a hand-lever connected to the collar, anadjustable collar mounted upon the slidable section of the rocking bar,and a spring interposed between said adjustable collar and a stationarypart of the machine, the rocking bar having a crank by which it isconnected to the connecting-rod of the cutting mechanism, substantiallyas shown and described.

In testimony whereof I afiix my signature, in the presence of twoWitnesses, at Glenwood, Indiana, April 1, 1901.

GEORGE W. HINGHMAN.
